Filed: 1940-12-20
Abstract: 544,598. Cooling cylinders. SPEAKE, H. P. Dec. 20, 1940, No. 17939. [Class 7 (ii)] An aircraft engine has "reverse-flow" cooling (the cooling air travelling forwardly past the part to be cooled) and a centrifugal fan for assisting in ejecting the cooling air after it has passed the part to be cooled. As shown, a cowling 11 surrounds a number of radiallyarranged banks of in-line cylinders 12 and the hub 13 of a tractor airscrew is provided with a spinner 14. Attached to the diaphragm plate 24 of the spinner is the centrifugal fan, which comprises annular plates 19, 20 of U-section, forming an annular passage in which fan blades 21 and short intervening blades 21a are radially arranged. The cooling-air may be drawn from the leading edge of the wing at the point of greatest pressure and passes in "reverse flow" over the cylinders. The escape from the fan is controlled by an adjustable gill ring 17, and the ends of the blades may be bent over to assist the air flow. Instead of being integral with the spinner, the fan may be mounted independently and driven from the engine or propeller shaft or by electric means.

Title: Control for a hydrostatic transmission
Inventor: BROOKS VERN EUGENE
IPC: F16H61/42
Filed: 1969-04-08
Abstract: 1,219,548. Hydrostatic transmission control. EATON YALE & TOWNE Inc. 8 April, 1969 [8 April, 1968], No. 17944/69. Heading F2D. In a control system for a vehicle hydrostatic transmission 11 wherein a manual control element is connected by a linkage to a lever 41 controlling the ratio of the hydrostatic transmission 11, the linkage contains a lost-motion connection which permits a spring assembly 120 to move the lever 41 to its neutral position when the manual control element is within a predetermined distance of its neutral position. A manual control lever 12 is connected through a linkage 30 ... 34 to a lever 35 fast with a stubshaft 36 and two pedals 13, 14 are also connected to the lever 35 through linkages 70, 80 so that rotation of the lever 12 from its neutral position 20c or depression of the pedal 13 or 14 rotates the lever 35 and stub shaft 36 in one direction or the other. The stub shaft 36 carries a lever 37 connected through a lost-motion spring coupling 40 to the lever 41 so that rotation of the stub-shaft 36 pivots the lever 41 to operate a control valve 43 which supplies pressure fluid to a follow-up servomotor 46 controlling the swash-plate of the hydrostatic transmission 11. The lost-motion in the linkage may be provided by a lost-motion connection between a rod 39 and the lever 41 or may be provided in the lost-motion spring connection 40. The spring assembly 120 is adjustably secured to the tractor by an eccentric mounting (Fig. 9, not shown). Adjustably positioned spring-pressed plungers (60), Figs. 2-4 (not shown), project into the path of the lever 12 to indicate to the driver that a predetermined ratio has been obtained. Additional effort is required to move the lever 12 past the plungers (60). A lost-motion spring coupling 33 in the linkage 30 . . . 34 between the lever 12 and lever 35 permit the latter to be rotated by the pedals 13, 14 without a corresponding movement of the lever 12. The pedals 13, 14 carry lugs 73, 83 engageable with arms 72, 82 fast with a sleeve 74 and shaft 75 carrying arms 78, 85 connected by links 79, 86 to the lever 35. On depression of one of the pedals, e.g. 13, the lug 73 engages the arm 72 and acts through the linkage to rotate the lever 35 anticlockwise. The rotation of the lever 35 acts through the linkage 86, 85, 75 to rotate the arm 82 clockwise. Sufficient clearance between the lugs 73, 83 and the arms 72, 82 is provided to prevent clockwise rotation of the arms 72, 82 effecting movement of the pedals 13, 14.

An apparatus for making glass fibres comprises a hollow centrifuging body 1 whose periphery includes a peripheral band 2 having rows of projection apertures 3 through which the molten glass is centrifugally projected as streamlets by the rotation of the body at high speed, the emerging streamlets being subjected to the action of flame or hot gas so as to produce very fine fibres, the top part 8 of the band being arranged in the path of the current of flame or hot gas and being so shaped that the portion of the current striking it will be directed outwardly towards the main part of the current so as to limit its deviation towards the top of the body. The top of the band may be truncated or rounded and maybe provided with an obstacle above the body and in the vicinity of the band for preventing or reducing deviation of flame or gas towards the top of the body. The obstacle may be an annular boss 7 on the body 1 or on the wall of an associated combustion chamber or burner which may penetrate into the interior of a recess in the wall of the chamber or burner, or in the top of the body. The band may have a variable conicity of which the angle made with the vertical increases from the top to the bottom of the band. The band may be formed of several superposed truncated cone surfaces 2a, 2b, 2c of which the angle made with the vertical increases from top to bottom. The band may have internal stiffening e.g. annular horizontal ribs 12, vertical ribs 13, or ribs directed along generatrices, and the external surface of the band may have ridges or protuberances, and may be in the form of tiers 10 each having one or more rows of apertures 3. The horizontal distance d between the tiers may increase with the slope of the band and the apertures may have a shape flared out towards the inside of the body, the band being formed of two concentric jointed elements 14, 17, the inner of of which 14 has the flared out inlets 15 of the apertures 3. The body may be of variable thickness, the thickness being greater at the bottom than at the top. The bottom 11 of the body may be inclined to the horizontal at an angle of 10 degrees and may have a profile similar to that of the top 6 of the body. Specifications 782,802 and 790,727 are referred to.
